﴿ فَلَمَّا رَءَا ٱلشَّمْسَ بَازِغَةًۭ قَالَ هَٰذَا رَبِّى هَٰذَآ أَكْبَرُ ۖ فَلَمَّآ أَفَلَتْ قَالَ يَٰقَوْمِ إِنِّى بَرِىٓءٌۭ مِّمَّا تُشْرِكُونَ ﴾

“Then, when he beheld the sun rising, he said, "This is my Sustainer! This one is the greatest [of all]!" - but when it [too] went down, he exclaimed: "O my people! Behold, far be it from me to ascribe divinity, as you do, to aught beside God!”

And when he saw the sun rising he said ‘This is my Lord; this is greater!’ than the star and the moon the masculine demonstrative pronoun hādhā ‘this’ is used for the feminine shams ‘sun’ because the predicate rabbī ‘my Lord’ is masculine. But when it set and the argument against them had become stronger and they still had not repented he said ‘O my people surely I am innocent of what you associate with God in the way of idols and accidental bodies which require an originator. They then asked him ‘What do you worship?’
